No. Reactivity to vinegar is an example of a chemical property.
Reactivity is a chemical property (in chemistry !).

No.
Kind of tricky question, because on the surface, one might not think that cornstarch and vinegar (acetic acid) don't react chemically. But, in fact, there can be a chemical reaction under the right conditions. So, it would probably be safe to say "chemical" change, if given the chance, but it could also be just a physical change if conditions aren't right.
No, because it just change to liquid
Yes ,Vinegar and any other element of the Periodic Table have a chemical and physical property.

physical- there's no chemical change.
Mixing flour and baking soda is a physical change; the process of mixing them together does not in itself cause them to change into any other chemical. However, when the pastry is baked, then there will be chemical changes.
its a chemical change because you cannot reverse the process and just have milk and vinegar separate
its a chemical change
